Cas McCullough has sung her way from preschool to parenthood, developing a love of performing on stage at age six when she sang nursery rhymes on TV with the Channel Seven Super Juniors in Adelaide. Now as a mother of  three boys, Cas performs original heartfelt ballads inspired by the ups and downs of her life's journey and motherhood.

Cas writes inspirational and Gospel songs in a variety of styles including folk, contemporary, country, jazz and blues.

In 2000, Cas began to write songs about birth and motherhood as a healing mechanism after the traumatic birth of her first child. In 2002 she began studying voice and composition under the guiding hand of Brisbane songstress and teacher Laine Loxlea Dannan and in 2003 Cas gave birth to baby no. two, and produced her first CD, Stranger’s City.

In February 2004 Cas performed her self-penned show "Birth Matters" which she produced in conjunction with photographer Deirdrie Cullen at the Summer Song emerging artists'  showcase at Metro Arts in Brisbane and made her debut at the Australian Gospel Music Festival in Toowoomba in April 2004. Cas also made her major production debut by producing the entertainment for the "Airing Our Laundry" mini-fest presented by the Friends of the Birth Centre (FBC) Queensland in King George Square, Brisbane, in May, 2004. Cas went on an extended performance break while the family welcomed their third baby boy in January 2005. However, in June 2005 Cas produced the entertainment for the FBC BIRTHday Festival at Roma Street Parklands featuring Barbara Fordham, The Peachfish, Kristy Wilson, Flipside Circus, and Laine Loxlea Dannan, an event which attracted around 3000 attendees.

Cas lives in Brisbane, Australia with her husband of nine years and her young family. She is a spokesperson for the national consumer advocacy group Maternity Coalition Inc. on issues related to vaginal birth after caesarean (VBAC), Post Traumatic Stress Disorder and Postnatal Depression, a participant in the Brisbane support group Birthtalk, and co-founder of Mums In Touch Forest Lake, a community-based support network for new and isolated mums.

Aside from her music career, Cas is also a published freelance writer in parenting magazines and a committed campaigner and speaker on birth care reform. She has a Bachelor of Arts degree majoring in English Literature and a Master’s degree in Business (Communication Studies) and now with 15 years PR experience behind her uses her professional skills to do pro bono PR and Marketing work for Maternity Coalition Inc. as well as work for grassroots arts organisations such as Flipside Circus.
